Mercedes-Benz M-Class: Spy shots?

Are these spy shots of the next-generation Mercedes-Benz M-Class?

It’s difficult to make out the exact make and models presented on the overcast day but there’s definitely a German theme going on. We initially suspected the larger crossover/SUV had a shape similar to the Porsche Cayenne and the taillights off the Volkswagen Tiguan, but the side mirrors, door handles, and wheels point towards a Mercedes-Benz origin. We believe this is the 2012 M-Class, which will continue to build the legacy of Mercedes’ most popular sport-utility vehicle.
